St Michael and All Angels is a Grade I listed church on the estate of the Duke of Beaufort in the village of Great Badminton, Gloucestershire, England. Attached to the Duke of Beaufort's residence, Badminton House, it is an active Anglican parish church in the diocese of Gloucester. Although within the grounds of the Badminton Estate, the church is owned, and its upkeep met, by the Badminton's Parochial Church Council, rather than the Ducal estate. There is a smaller church of the same name in the neighbouring hamlet of Little Badminton.

Duke of Beaufort is a title in the Peerage of England. It was created by Charles II in 1682 for Henry Somerset, 3rd Marquess of Worcester, a descendant of Charles Somerset, 1st Earl of Worcester, legitimised son of Henry Beaufort, 3rd Duke of Somerset, a Lancastrian leader in the Wars of the Roses. The name Beaufort refers to a castle in Champagne, France. It is the only current dukedom to take its name from a place outside the British Isles.
